Tx ID as Asset ID (#926)

Browse Source 
* Allow AssetLinks to be used in place of Assets in the Transaction Model and enforce `Transaction.transfer()` to only take an AssetLink

* Remove AssetLink's inheritance from Asset

* Remove id from the Asset model

* Fix get_txids_by_asset_id query for rethinkdb after removing asset's uuid

Because `CREATE` transactions don't have an asset that contains an id
anymore, one way to find all the transactions related to an asset is to
query the database twice: once for the `CREATE` transaction and another
for the `TRANSFER` transactions.

* Add TODO notice for vote test utils to be fixtures

* Update asset model documentation to reflect usage of transaction id

* Fix outdated asset description in transaction schema
